Investigations on the incidence of septate gregarines in shrimp have immense importance because of severe pathogenicity of the parasite. The septate gregarines infect the midgut of shrimp Peneaus monodon and severe infection disturbs the intestinal tissues. Mostly gregarines of the genus Nematopsis have been identified from cultured peneaid shrimp. It has worldwide in distribution. In India, gregarine parasites have so far been reported from penaeid shrimps of Bombay and Kerala. The species which was isolated from the midgut of shrimp Peneaus monodon collected from Kharibari area of Sunderbans. 9 out of 20 i.e. 45% of the randomly sampled hosts were found to be infected with a species of the genus Nematopsis. Different developmental stages including trophozoites, sporadins, and gametocysts of the Nematopsis sp. infecting the shrimp have been isolated. No correlations have been established between incidence of infection and environmental parameters.
由于该寄生虫具有严重致病性，对虾中分隔簇虫发病率的调查具有极其重要的意义。分隔簇虫感染斑节对虾的中肠，严重感染会扰乱肠道组织。在养殖对虾中，大多已鉴定出的簇虫属于线虫簇虫属。它分布于世界各地。在印度，迄今已报道孟买和喀拉拉邦的对虾感染了簇虫寄生虫。该物种是从苏达班斯哈里巴里地区采集的斑节对虾中肠分离出来的。在随机抽样的20只宿主中，有9只（即45%）被发现感染了线虫簇虫属的一个物种。已分离出感染对虾的线虫簇虫属的不同发育阶段，包括滋养体、孢子体和配子囊。感染发生率与环境参数之间尚未建立相关性。
